Ferrosilicon 45 thiab ferrosilicon 65 -} yog silicon-hlau alloys nrog cov ntsiab lus sib txawv ntawm silicon cov ntsiab lus, muaj pes tsawg leeg thiab muaj cov ntawv thov.
Ntawm no yog cov ncauj lus piav qhia:
1. Silicon cov ntsiab lus thiab muaj pes tsawg leeg
Ferrosilicon 45: muaj 45% silicon, nrog cov ntsiab lus carbon ntau dua (feem ntau 2-3%) thiab ntau dua impurities xws li sulphorus. Qhov seem - yog hlau.
Ferrosilicon 65: Muaj 65% silicon, ho txo cov ntsiab lus ntawm cov khoom sib dhos rau kev xaiv cov ntaub ntawv raw thiab tswj cov txheej txheem.
2. Lub cev cov yam ntxwv
Xim thiab kev ntxhib los mos: Ferrosilicon 65 yog lub ntsej muag txho ntau dua ferrosilicon 45 (uas tsaus ntuj nti li ferrosilicon 75.
Melting taw tes: nws melting taw tes yog qis dua li ferrosilicon 45 tab sis siab dua ferrosilicon 75, uas cuam tshuam rau nws qhov kev ua ntsuas kub hauv kev siv cov ntawv thov.
3. Daim Ntawv Thov
Ferrosilicon 45:
Cov hlau melting: siv ua deoxalizer kev lag luam tshem tawm oxygen los ntawm Molten hlau, txhim kho kom zoo.
Cam khwb cia hlau: tswj cov pa roj carbon rau silicon piv rau hauv grey cam khwb cia hlau thiab lwm yam khoom nrhiav khoom.
Ferrosilicon 65:
Tshwj xeeb cov alloys: siv rau kev tsim cov alloys alloys (nce floys thiab kub ua kom zoo nkauj) thiab cov khoom sib nqus (nce cov khoom sib nqus).
Qib nrab lub luag haujlwm: Ua raws li tus choj ntawm Ferrosilicon 45 thiab 75 hauv cov ntawv thov uas xav tau cov khoom lag luam silicon, xws li qee yam sib tw me me lossis nruab nrab mellurgical cov txheej txheem.
4.Production Txheej Txheem
Ferrosilicon 65: Yuav tsum muaj hluav taws xob ntau dua arc kom sov dua Ferrosilicon 45, siv cov neeg sawv cev nqaij daim tawv nqaij quarvoling kom ua tiav cov pa roj carlicon ntau dua. Txawm li cas los xij, nws yog tsawg dua lub zog sib zog dua ferrosilicon 75 ntau lawm.
Ferrosilicon 45: Ua nrog cov qauv nruj me me cov qauv khoom siv thiab cov nqi qis dua, ua ntej them tus nqi kev coj dawb huv.
